The spout 3 is exteriorly is invention relates to closures for disthreaded near its closed outer end as indipenslng tubes such for example as tubes decated by the numeral 6, the threads extendthreaded on to the discharge spout of the tance above the discharge orifice 5 for a purtube and which must be completely removed pose to be presently explained.

The present invention, therefore, thecap will bear snugly against the upper alms to provide a closure of the class de-- surfaceof the closed end 2 of the tube 1 scribed so constructed that the contents of andcompletely surround the lower end of V spout that it cannot be removed without. threadlng the cap until the threads upon ventlon cannot be lost and its presence upon cap may be slid outwardly upon the. said embodied 1nthe construction of an ordispout so tha thethreads may be again nary collapsible paste tube. 1
